Imagine a vehicle that can conquer the toughest terrains, shrug off the harshest conditions, and still feel like a five-star hotel on wheels. That’s the Stone Offroad Design (SOD) Peak 6x6, a beastly Mercedes-based RV that’s redefining what it means to hit the open road. Built for those who crave adventure without sacrificing comfort, this machine is as much a fortress as it is a home, making it the ultimate ride for anyone dreaming of exploring the wildest corners of the world.
A Beast Built for the Wild
The SOD Peak 6x6 is no ordinary RV. It’s a 33-ton, six-wheel-drive monster designed to tackle the kind of terrain that would leave most vehicles stranded. Based on the Mercedes-Benz Arocs, a heavy-duty truck typically used for hauling construction equipment, this RV is powered by a massive 15.6-liter six-cylinder diesel engine pumping out 580 horsepower. That’s enough muscle to climb steep hills, ford deep rivers, and power through mud, sand, or snow without breaking a sweat. For those who prefer a slightly different flavor, SOD also offers a version built on the MAN TGS 33.520 chassis, with a still-impressive 520 horsepower.

What makes this vehicle stand out is its rugged engineering. The chassis is hot-dip galvanized, meaning it’s built to resist rust and corrosion even in the harshest environments. A custom subframe with a double three-point suspension system keeps the ride stable, no matter how rough the ground gets. Add in a hydraulic leveling system, and the SOD Peak 6x6 can park on uneven terrain and still provide a perfectly level living space. Whether it’s a rocky mountainside or a sandy desert dune, this RV stays steady, ensuring you can kick back in comfort after a day of exploration.

The exterior is just as tough as the engine under the hood. Six massive off-road wheels grip the ground, while steel plates along the lower half of the vehicle add extra protection. A roof railing system and a front-mounted trailer hitch (nicknamed the “Wal Bar”) make it easy to haul gear or even tow another vehicle. At the back, a remote-controlled lift is a game-changer, letting you load up quad bikes, spare wheels, or other heavy-duty equipment without breaking a sweat. It’s the kind of setup that makes you feel ready for anything—whether it’s a cross-country adventure or, as some have joked, a zombie apocalypse.
A Luxury Retreat on Wheels
Step inside the SOD Peak 6x6, and the rugged exterior gives way to a living space that feels like a high-end cabin. The 21-foot-long motorhome box is crafted with fiberglass-sandwich construction and foam insulation, keeping the interior cozy in any climate. With walls ranging from 2.4 to 3.1 inches thick, it’s built to withstand extreme weather while keeping noise and temperature under control. The layout is thoughtfully designed, with every inch of the 6.5-meter-long living area optimized for comfort and convenience.

The interior is where the SOD Peak 6x6 really shines. Hand-stitched leather seats with honeycomb quilting, real wood cabinetry, and granite countertops create an atmosphere that’s more cigar lounge than campsite. The dashboard, side panels, and headliner are wrapped in a mix of leather and Alcantara, giving the driver’s cab a premium feel that matches the living space. A custom sound system, complete with specialized insulation for crystal-clear audio, ensures you can enjoy your favorite tunes no matter where you are.

The living area is packed with features that make it feel like home. A semi-enclosed rear bedroom features a raised double bed, perfect for unwinding after a long day on the trail. The kitchen is equipped with modern appliances seamlessly integrated into the cabinetry, including a full-size refrigerator, freezer, and a four-burner induction cooktop. A dining area sits nearby, with plenty of storage cabinets overhead to keep your gear organized. The bathroom is split into two zones: a combined shower and toilet area, and a separate sink section with a floating vanity that wouldn’t look out of place in a luxury hotel. For extra sleeping space, there’s a sleeper compartment above the cab and a foldable bed over the lounge area, making room for up to four people.

Natural light floods the interior through four 1000 x 500 mm windows and three tempered glass roof hatches, all equipped with blackout shades and insect screens. A robust entry door with an insect screen blind and a coded central locking system keeps the cabin secure, while two large storage flaps provide easy access to gear. Every detail, from the hand-stitched leather handles to the knotty-grained wood accents, shows the level of craftsmanship that SOD’s team of master builders puts into each vehicle.
Built for Adventure, Designed for You
One of the standout features of the SOD Peak 6x6 is its customizability. Stone Offroad Design, based just south of Munich, Germany, prides itself on creating vehicles tailored to each owner’s needs. Buyers can choose their own color schemes for the interior and exterior, pick out specific fittings, and even influence the layout of the living space. Want a different wood finish or a custom leather pattern? SOD’s team of experienced craftsmen can make it happen. Every vehicle is built with TÜV approval, ensuring it meets strict German safety and quality standards.

The Peak 6x6 isn’t just about luxury—it’s about self-sufficiency. A 1.6kW solar electric system and a 150-amp generator keep the power flowing, while a 1,000-liter freshwater tank and a 16-liter hot water boiler ensure you’ve got plenty of water for cooking, cleaning, and showering. An independent air conditioning system keeps the cabin cool, and underfloor heating adds warmth on chilly nights. Whether you’re parked in the middle of the desert or high in the mountains, this RV is designed to keep you comfortable and independent for days on end.
The Ultimate Expedition Machine
The SOD Peak 6x6 isn’t just a vehicle—it’s a statement. It’s for those who want to go where others can’t, without giving up the comforts of home. With a starting price of around 1.5 million euros (roughly $1.6 million USD), it’s a serious investment, but for those who can afford it, it’s hard to imagine a better way to explore the world. The combination of a battle-ready chassis, off-road prowess, and a luxurious interior makes it a standout in a market dominated by brands like Action Mobil and Unicat.

Stone Offroad Design has taken the expedition RV concept and turned it into something that feels both timeless and cutting-edge. The Peak 6x6 is as photogenic as it is capable, blending rustic charm with modern tech in a way that’s sure to turn heads, whether you’re parked at a remote campsite or cruising through a bustling city. It’s the kind of vehicle that invites you to dream big—whether that’s crossing continents, chasing sunsets, or just getting away from it all.
For those who’ve ever wanted to live life on their own terms, the SOD Peak 6x6 is more than just an RV. It’s a ticket to freedom, a mobile basecamp that can take you anywhere, and a reminder that adventure doesn’t have to mean sacrifice. With its blend of power, toughness, and luxury, this is one vehicle that’s ready for whatever the road—or lack thereof—throws its way.
